@Carmel: It's not meant to check your answers. It only shows up red if the number you enter cannot be split into valid pairs (eg the number has an odd number of digits or one of the pairs of digits is greater than 20).

The script for checking the answers doesn't work properly

Great puzzle problems! Hint on #9: try starting with an analogous problem using smaller numbers (e.g. 3a + 10b). This helped me to see what I had to do more generally.

@Seth: try solving it for 3a+4b, 3a+5b, 4a+5b, etc and look for patterns

Loved these puzzles! I have no idea how to approach #9, though. Will the solutions be posted at any point? Or, can anyone provide a hint to how to approach it?
